Culture Rework: Barbarian (or Industrial
With the barony's ability to create outpost with scouts, I cannot help but see a society reork in the future. At first glance it would be easy to assume Barbarian, because on of their unique traits is becoming more generalized. In fact, I highly believe this to be the most likely one to be reworked.
But with the inclusion of trade networks, I cannot help but think about Industrious. With the sheer amount of production they have, it makes it possible for a new Industrious subculture to come out and capitalize (heh) on this new market. It would probably become a powerful trading partner entirely because it floods the markets with their products, allowing a unique way to play the competitive merchant personality through industrial strength.
I haven't really thought these out much, but my gut tells me a culture rework will involve one of these two next.
